Summary

[edit]
Description

Naval Facilities Engineering Command Washington educated residents near the U.S. Naval Observatory about light pollution June 1 at the annual Glover Park Day. Light pollution affects the Naval Observatory’s ability to view the night sky when light shines upwards or is reflected off clouds and low atmosphere.

“Folks in Glover Park were very happy to see the Navy show up as part of the community,” said Richard Owen, NAVFAC Washington. “We’ve reached out to the city about light pollution, but it’s also important to talk to our neighbors in the city.”

Owen and other civilian and military representatives advised booth visitors on how they could help. Low pressure sodium lamps are the only types with an electromagnetic spectrum that can be filtered by telescopes at the Naval Observatory. Neighborhood residents were encouraged to use “full cut-off” light fixtures, which do not allow light to be directed above its horizontal plane, and to limit the amount of exterior light in urban areas. Doing so will reduce energy use and expense, creating a more environmentally sustainable city, they said.
